The basic problem with carbon trading is that it doesn't produce the right effect. People who didn't want to produce the stuff get paid by people who shouldn't be producing it. That means we get more CO2 produced than we should and someone is getting paid for making us feel better about it. They're not actually 'selling' anything - but coffin nails, possibly.

Right; except it is not the people who get paid. The money never leaves the system. Its like a black hole; money goes in; nothing comes out.

Not only four years but it is in our hand how to save earth. If you not pollute our envelopment then earth will save more then four years. And I really thanks to United States Government because they doing very good projects about save our environment.
